CNN:

The Justice Department announced Friday it is revising a decades-old definition of rape to expand the kinds of offenses that constitute the crime and for the first time, include men as victims.
Now, any kind of nonconsensual penetration, no matter the gender of the attacker or victim, will constitute rape -- meaning that attacks on men will be counted.
The crime of rape will be defined as "penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, without the consent of the victim," a Justice Department statement said.
Attorney General Eric Holder said the new definition will lead to a more comprehensive reporting of rape in the FBI's annual compilation of crime statistics.
